The nutritionist: 'Eat a chocolate bar every day to stay happy'

Chocolate is good for our mental health. It contains serotonin and phenylethylamine, both of which are mood-lifting agents found naturally in the human brain, released when we?re feeling happy or in love. And the even better news is, we need enough to get the effect! So a 30g bar of dark, 70 per cent chocolate is the best way to put you in a good mood.
